ABSTRACT:
A process and apparatus for preparing a homogeneous dissipation of a viscous, liquid-dissipatable polymer. The process comprises continuously feeding molten polymer into a first inlet of a mixing chamber, feeding a stream of a relatively low viscosity dissipating liquid into a second inlet of said mixing chamber at an angle, at a velocity and at a flow rate relative to the structure of said chamber such that shearing action is created at the advancing end of the polymer to continuously erode the end of the polymer, and further mixing the polymer and dissipating liquid downstream from an outlet of the chamber to form a homogeneous dissipation of polymer in dissipating liquid.
